To all ac/"10m it may concern:

Be it known that I, Join: R. WARREN, a citizen of the United States, residing at llrand Rapids, in the county of Keiit and tilate of Michigan, have invented new and useful Improvements in Guiding Devices,"ot which the following is a specification.

The present invention relates to guiding devices, particularly such as may be em ployed to guide a cylinder, of an internalcombustion engine, having a longitudinal ing six cylinders, three of which and the l 7-, ename s frame areshown partially sectioned in a diametrical plane of the cylinders, to guiding device" is applied which engine my Figure 2 1s a transverse sectional view of the upper portion of the same taken on line 2'2 of Figure 1; v Figure 8 is a sectional vieu'r of the guiding device andadjacent partstakerionline 3-- 3 of Figure 4;

Figure 4 is a sectional view of the same taken on line 4 4 of Figuiefii;

Figure 5 ,is a View thereof sectio r'ied on line 55 of Figure 4 Figure 6 is a section the same taken on line" 6-''6' of Figure Figure 7 is an outerend new of a ent means Figure 8 is an opposite end view there of; and s Figure 9 is a side'view of thesa-me; In the embodiment of the inventionchoseri for illustration by the drawings and for detailed description in. the body of this'spec ification, my guiding device isshown apl f a slight distance in its bearings 10, but its lower end is pressed toward the right-hand side of Figure" 1, a rockin'g movement about plied to an internal-combustion engine o the four-cycle type" havin'g'six cylinders, 1, 2 and 3' thereof appearing partially sectioned which a View of para of diametrically in Figure 1,- three cylinders being formed in each of the tire cylinder blocks 4', and the cylinders having pistons and connecting rods 7 for operating the cranks respectively on the crank shaft or engine shaft 6. At their upper ends, the cylinders have ports 61 for the admission of the operating fluidthereinto and for the expulsion of the products of combustion therefrom. trolling the admission of the operating fluid to the cylinders and for permitting the expulsion of the products of combustion therefrom rotates in a' hearing or valve chamber in a split valve-casing designated generally 16, having ports communicating throu'glithe' cylinders said ports respectivesuch valve-casing comprising an upper portion 8 supported in connection with the engine frame 14* and a lower portion 9 supportedin connection with the cylinders of the cylinder blocks." These cylinder bloc s have a slight mox ement in the cylinders loiigitiidinal' direction in bearings 10 on the frame, such movement's being caused by varying" pressures' in the cylinders as em plained in Patent No. 1,449,469 issued March 27, 1923 on my application.

In the construction shown, the valve-Gas ing' 16 has a bushing 34 surrounding the valve uon rotatively and provided vvith openings which register \vith the cylinders ports respectively. The valve is hel loiv,- havinglongitudinallyextending passages not shown) to which the fluid is supplied from a vent 26 in the frame, the fluid thence passing through a series of inlets 51 through the valves' all and to each cylinders port through openings 28 in the valves Wall; the products" of combustion beingdischarged from each cylinder through outlets 30 through the valves Wall and into its longitudinally-extending passage 32 open ing'at the" end or ends of the valve through a centrally-disposed outwardly-extending exhaust nozzle 11 communicating with the 'exhaustpipe53.

It is evident that when, in the cycle of The rotary valve 15, for con-- an axis extending horizontally through the cylinder block in the transverse direction of the valve thus taking place with the alternate firing strokes in cylinders 1 and 8.

In the application of my guiding device shown in the present example, this rocking movement is resisted and the slight longitudinal movement of the cylinders may be trued to the proper line. In this example, the cylinders 1, 2, 8 are provided with one or more (two in the construction shown) downward extensions or members 12 mov able with the cylinders and guided by my device. This device comprises guide members or blocks 18 movable relatively to a fixed member-the engine frame 14-in a direction inclined to the movement of the cylinders e. of the members 12), means being provided for securing blocks or guide members 18 in desired adjusted position against said inclined movement, such means in the construction shown being a threaded clamping bolt. To effect this inclined movementinto its adjusted position and to secure the guide member in said position, it is pro vided with a slide bearing 17 extending in the line of its said inclined movement, fixed guide means extending into and slidably bearing in said bearing. As particularly shown in Figures 8, 4, 6, 7, 8 and 9, the fixed member (the engine frame 14:) has an opening 18 through which the guide means, a cylindrical plug 19 rotatably fitting in said opening, extends. This guide means has a flattened inner end portion 20, slidably guidingly fitting in the slide bearing 17, and has an axially extending opening 21 through which extends the clamping bolt 22 screwthreaded in the block or guide member 18, and a head 28 outside the frame 1 1, whereby the bolt may be screwed down to clamp the flange 24 of the cylindrical guide means and the guide member 18 securely to the frame 14. The opening 21 in the guide means 19 is elongated as seen in Figures 1, 6, 7 and 8 to permit the movement of the block 18 in the aforesaid inclined direction to its adj usted position.

It will be understood that when the blocks 18 are moved to and secured in their adjusted position, they cannot be moved therefrom by the movement of the cylinders and vibrations of the machine, owing to the acute angle between the cylinders longitudinal movement and the bearing 17 of the guide blocks 18; and that the adjustment of these guide blocks may be made from outside the engine frame 14; and it is also evident that my guiding device may be employed in connection with other mechanisms as well as with that illustrated by the drawings.

The invention being intended to be pointed out in the claims, is not to be limited to or by details of construction of the particular embodiment thereof illustrated by the drawings or hcreinbeforc shown or do scribed.

I claim:

1. In a guiding device: a movable memher; a member fixed relatively thereto; a pair of guide members slidably contacting the opposite sides of the movable member for guiding the same and movable relatively to the fixed member in a direction inclined to the movable members movement; means for securing the guide members against movement relatively to the fixed member.

2. In a device of the character described: a movable member; a member fixed relatively thereto; a pair of guide members slidably contacting the opposite sides of the movable member for guiding the same and having slide bearings inclined to the direction of the movable members movement; guide means slidably bearing in the guide members bearings; means for securing the guide members against movement relatively to the fixed member.

8. In a device of the character described: a movable member, a member fixed relatively thereto and having an opening; a guide member for guiding the movable member and having a slide bearing inclined to the di rection of the movable members movement; guide means for guiding the movable member; a. bolt extending through said opening and in threaded relation with the guide member.

4. In a device of the character described: a movable member; a member fixed relatively thereto and having an opening; a guide member for guiding the movable member and having a slide bearing inclined to the direction of the movable members movement; guide means extending through said opening and slidably bearing in the guide members bearing and having an open ing; a bolt extending through the guide means opening and in threaded relation with the guide member, and adapted to clamp the guide member, guide means and fixed member together.

5. In a device of the character described: a movable member; a member fixed relative- 1y thereto and having an opening; a guide member for guiding the movable member and having a slide bearing inclined to the direction of the movable members movement; guide means extending through and rotatably bearing in said ably bearing in the guide members bearing and having an opening; a bolt extending through the guide means opening and in threaded relation with the guide member, and adapted to clamp the guide member, guide means and fixed member together.

In testimony whereof I have hereunto set my hand at Grand Rapids, Michigan, this 5th day of November, 1928.
